PTC Resettable Fuses have become an increasingly popular alternative to traditional fuses due to their ability to automatically reset once the current has decreased to a normal level. The YM120C80N101 is a PTC Resettable Fuse that is well-suited for various applications.The YM120C80N101 is mainly used in consumer electronics and electrical power systems for circuit protection and efficient current flow control. It can be used in a wide range of applications, from protecting USB connections in laptops and cell phone chargers, to safeguarding automotive systems and household appliances.When the current exceeds the rated current measured at the YM120C80N101 switch, a polymer element inside the switch begins to heat up and quickly adjusts the contact point of the switch. This temporarily disrupts the circuit and prevents further damage, which is when notifications such as “device overloaded” or “reset the device” are displayed. When the current has dropped to normal, the polymer element\'s temperature will cool down and the switch\'s contact point will return to its original position, allowing normal circuit functionality once again. The number of times the PTC resettable fuse can be reset and reused is unlimited, making it much more efficient than a traditional fuse which can be used only once.The YM120C80N101 is also widely use in the telecom industry due to its high heat and corrosion resistance. It features punch-down, reverse U, tin drop and gate terminals which are easier to connect and install than traditional fuse blocks and clips, allowing them to be used in much smaller spaces.It is also considered to be one of the safest PTC resettable fuses, as it can withstand high temperatures up to 1000°C and can handle 40-80 Amps of current. This makes it a highly durable and reliable choice for applications in various industries.Due to all of these features, the YM120C80N101 is an ideal choice for a wide range of applications. It is one of the most reliable and efficient PTC resettable fuses on the market and is widely used in many industries.
